By taking and testing a small sample of a person’s blood, doctors can check for many kinds of diseases and conditions. Blood tests help doctors check how the body’s organs are working and see if medical treatments are helpful.
To help your child get ready for a blood test, find out if they need to fast (not eat or drink) or should stop taking medicines before the test. Explain what to expect during the test. If your child is anxious about it, work together on ways to stay calm.
A glucose test measures how much glucose (GLOO-kose) is in the blood. Glucose is a type of sugar the body uses for energy.
Doctors do glucose tests to check for low or high levels of glucose. Sometimes it's done as part of a routine checkup to screen for problems, and sometimes because a child has not been feeling well.
A low glucose level is called hypoglycemia. A high level of glucose is called hyperglycemia. Diabetes is one thing that can cause high glucose levels.
If you have questions about the glucose test or what the test results mean, talk to your doctor.
